There is the following question on a practice test:

Which service are you addressing by installing a RAID array and load balancer?

A. Confidentiality

B. Availability

C. Accountability

D. Integrity

The correct answer according to practice test is "Integrity".

Can someone explain this and why it would not be "Availability"? I'm not understanding how availability wouldn't be the correct choice.

    A raid array allows one or more drives to go bad without losing the data. So it preserves the integrity of the data. – pcalkins May 20 '20 at 18:03

    I don't think "Availability" is a wrong answer, though. Seems just as valid. – pcalkins May 20 '20 at 18:44

    @pcalkins: I also think that availability is also addressed. If one of drives fails, it can be swapped without shutting down the whole system. This improves the availability. – mentallurg May 20 '20 at 18:59

    With most of these certifications, right and wrong are irrelevant. As best you can, give them the answer they want in order to pass the test. – user10216038 May 20 '20 at 21:11

By combining RAID with a load balancer, the question is asking about "Availability".

This appears to be a mistake in the answer. I doubt very much that CompTIA expects that "Integrity" is the intended answer.

I have taken over a couple of dozen certification exams and thousands of practice questions. It is very, very common for there to be mistakes. Your best response is to do what you've done: understand why the answer is the answer and not just memorise the answers.
